Aside from being one of the few 4K monitors available at the moment, it also boasts a 10-bit RGB "deep colour" technology, LED back-lighting, dual-HDMI ports and a 176-degree horizontal and vertical viewing angle.

At 35mm, it is also the thinnest 4K Ultra HD monitor on the market today.

Maxing out the credit card

Although there's no word on price, the PQ321 is unlikely to be kind to your budget. Recent 4K TV announcements have included prices in the £4,000-£5,000 (about AU$6,330-AU$7,920, US$6,100-US$7,630) range.

Asus is also expected to showcase another 39-inch, 4K Ultra HD monitor at the Computex 2013 trade show in Taipei this year.
